Gall Bladder

Introduction

Gall Bladder cancer is a rare disease in which malignant (cancer) cells are found in the tissues of thegallbladder. The gallbladder is a pear-shaped organ that lies just under the liver in the upper abdomen. The gallbladder stores bile, a fluid made by the liver to digest fat. When food is being broken down in the stomach and intestines, bile is released from the gallbladder through a tube called the common bile duct, which connects the gallbladder and liver to the first part of the small intestine.

Anatomy of the gallbladder. The gallbladder is just below the liver. Bile is stored in the gallbladder and flows through the cystic duct and the common bile duct into the small intestine when food is being digested.

The wall of the gallbladder has 3 main layers of tissue.

Mucosal (inner) layer.

Muscularis (middle, muscle) layer.

Serosal (outer) layer.

Between these layers is supporting connective tissue. Primary gallbladder cancer starts in the inner layer and spreads through the outer layers as it grows.

There are three ways that cancer spreads in the body.

Through tissue. Cancer invades the surrounding normal tissue.

Through the lymph system. Cancer invades the lymph system and travels through the lymph vessels to other places in the body.

Through the blood. Cancer invades the veins and capillaries and travels through the blood to other places in the body.

When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer

Risk Factor

Gall-Stones

Porcelain gall-bladdder

Choledochal cyst

Abnormal union of pancreatic & bile duct

Adenomatous gall-bladder polyp

Primary Sclerosing Cholangitis

Obesity

Salmonella Typhi infection

Symptoms

Possible signs of gallbladder cancer include jaundice, pain, and fever

Diagnosis & Staging

Gallbladder cancer is difficult to detect and diagnose early for the following reasons:

There aren't any signs or symptoms that can be seen in the early stages of gallbladder cancer.

The symptoms of gallbladder cancer, when present, are like the symptoms of many other illnesses.

The gallbladder is hidden behind the liver.

Gallbladder cancer is sometimes found when the gallbladder is removed for other reasons. Patients with gallstones may develop gallbladder cancer

Procedures that make pictures of the gallbladder and the area around it help diagnose gallbladder cancer and show how far the cancer has spread. The process used to find out if cancer cells have spread within and around the gallbladder is called staging.

In order to plan treatment, it is important to know if the gallbladder cancer can be removed by surgery. Tests and procedures to detect, diagnose, and stage gallbladder cancer are usually done at the same time. The following tests and procedures may be used:

Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patientâ€™s health habits and past illnesses and treatments will also be taken.

Liver function tests : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by the liver. A higher than normal amount of a substance can be a sign of liver disease that may be caused by gallbladder cancer.

CT scan (CAT scan):

Ultrasound exam:

Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.

ERCP (endoscopic retrograde cholangiopancreatography): A procedure used to x-ray the ducts (tubes) that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine. Sometimes gallbladder cancer causes these ducts to narrow and block or slow the flow of bile, causing jaundice. AnÂ endoscopeÂ (a thin, lighted tube) is passed through the mouth,esophagus, and stomach into the first part of the small intestine. AÂ catheterÂ (a smaller tube) is then inserted through the endoscope into the bile ducts. A dye is injected through the catheter into the ducts and an x-ray is taken. If the ducts are blocked by aÂ tumor, a fine tube may be inserted into the duct to unblock it. This tube (orÂ stent) may be left in place to keep the duct open. Tissue samples may also be taken.

Laparoscopy : A surgical procedure to look at the organs inside the abdomen to check for signs of disease. SmallÂ incisionsÂ (cuts) are made in the wall of the abdomen and aÂ laparoscopeÂ (a thin, lighted tube) is inserted into one of the incisions. Other instruments may be inserted through the same or other incisions to perform procedures such as removing organs or taking tissue samples for biopsy. The laparoscopy helps to find out if the cancer is within the gallbladder only or has spread to nearby tissues and if it can be removed by surgery.

Biopsy : The removal of cells or tissues so they can be viewed under aÂ microscopeÂ by apathologistÂ to check for signs of cancer. The biopsy may be done after surgery to remove the tumor. If the tumor clearly cannot be removed by surgery, the biopsy may be done using a fine needle to remove cells from the tumor.

Treatment

Treatment may also depend on the age and general health of the patient and whether the cancer is causing symptoms.

Gallbladder cancer can be cured only if it is found before it has spread, when it can be removed by surgery. If the cancer has spread,Â palliative treatment can improve the patient's quality of life by controlling the symptoms and complications of this disease

Three types of standard treatment are used:

Surgery

Gallbladder cancer may be treated with a cholecystectomy, surgery to remove the gall bladder and some of the tissues around it. Nearby lymph nodes may be removed. A laparoscope is sometimes used to guide gallbladder surgery. The laparoscope is attached to a video camera and inserted through anincision (port) in the abdomen. Surgical instruments are inserted through other ports to perform the surgery. Because there is a risk that gallbladder cancer cells may spread to these ports, tissue surrounding the port sites may also be removed.
If the cancer has spread and cannot be removed, the following types of palliative surgery may relievesymptoms:

Surgical biliary bypass: If the tumor is blocking the small intestine and bile is building up in the gallbladder, a biliary bypass may be done. During this operation, the gallbladder or bile duct will be cut and sewn to the small intestine to create a new pathway around the blocked area.

Endoscopic stent placement: If the tumor is blocking the bile duct, surgery may be done to put in a stent (a thin, flexible tube) to drain bile that has built up in the area. The stent may be placed through a catheter that drains to the outside of the body or the stent may go around the blocked area and drain the bile into the small intestine.

Percutaneous transhepatic biliary drainage: A procedure done to drain bile when there is a blockage and endoscopic stent placement is not possible. AnÂ x-ray of the liver and bile ducts is done to locate the blockage. Images made by ultrasound are used to guide placement of a stent, which is left in the liver to drain bile into the small intestine or a collection bag outside the body. This procedure may be done to relieve jaundice before surgery.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer.Â Internal radiation therapyÂ uses aÂ radioactivesubstance sealed in needles,Â seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type andÂ stageÂ of the cancer being treated.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injectedÂ into aveinÂ or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into theÂ cerebrospinal fluid, anÂ organ, or a bodyÂ cavityÂ such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated

Treatment Options for Gallbladder Cancer

Localized Gallbladder Cancer

Treatment of localized gallbladder cancer may include the following:

Surgery to remove the gallbladder and some of the tissue around it. Part of the liver and nearbylymph nodes may also be removed. Radiation therapy with or without chemotherapy may follow surgery.

Radiation therapy with or without chemotherapy.

Unresectable, Recurrent, or Metastatic Gallbladder Cancer

Treatment of unresectable, recurrent, or metastatic gallbladder cancer is usually within a clinical trial. Treatment may include the following:

Percutaneous transhepatic biliary drainage or the placement of stents to relieve symptoms caused by blocked bile ducts. This may be followed by radiation therapy as palliative treatment.

Cure : This is the most important goal of cancer surgery. In fact as a cancer patient you are also strongly willing to have cure of cancer for forever. For most of the Liver & Gastro-intestinal cancers perhaps surgery is the first step for cure. Radiation &/or Chemotheray may be advised as an additional tool to achieve this goal.

Control : If your cancer is at a later stage or if previous treatments have been unsuccessful, we aim to control your cancer by removing as much as safely possible. Once you recover from surgery, radiation or chemotherapy is advised as important tool to control your cancer.

Comfort : If you have an advanced stage of cancer or one that hasn't responded to treatments and having symptoms because of tumor i.e pain, jaundice, vomiting, bleeding either in vomitus or in stool, then our multi-specialist team work together to sure you are free of pain and other symptoms.

Role of Surgery for Cancer treatment

Surgery can be done for many reasons for treatment of cancer.

Curative Surgery

Curative surgery is done when cancer is found in only one area, and it’s likely that all of the cancer can be removed. In this case, curative surgery can be the main treatment. It may be used alone or along with chemotherapy or radiation therapy, which can be given before or after the operation.

Diagnostic & Staging Surgery

This type of surgery is used to take out a piece of tissue (biopsy) to find out if cancer is present or what type of cancer it is. The diagnosis of cancer is made by looking at the cells under a microscope. Staging surgery is done to find out how much cancer there is and how far it has spread. The physical exam and the results of lab and imaging tests are used to figure out the clinical stage of the cancer. But the surgical stage (also called the pathologic stage) is usually a more exact measure of how far the cancer has spread. Examples of surgical procedures commonly used to stage cancers, like laparoscopy or laparotomy.

Palliative Surgery

This type of surgery is used to treat problems caused by advanced cancer. It is not done to cure the cancer. For example, cancers of intestine may grow large enough to block off (obstruct) the intestine, or tumor is bleeding and unable to control bleed by medical/endoscopic technique. If this happens, surgery can be used to remove the blockage/control bleeding.

Approach for Surgery:

How surgery is performed? (Special surgery techniques): Open Or Laparoscopic

Open Surgery:

It is the Gold Standard approach for Liver & Gastro-Intestinal cancer. An incision is given on the belly depending upton the underlying location of tumor so that surgeon can directly approach the cancer on cutting the belly. Open Surgery help to remove tumor safely if its adherent to near by blood vessels or organ, that is otherwise difficult in laparoscopic surgery.

Laparoscopic Surgery

A laparoscope is a long, thin, flexible tube that can be put through a small cut (incision) to look inside the body. In recent years, doctors have found that by creating small holes and using special instruments, the laparoscope can be used to perform surgery without making a large cut. This can help reduce blood loss during surgery and pain afterward. It can also shorten hospital stays and allow people to heal faster.

The role of laparoscopic surgery in cancer treatment is not yet clear. Doctors are now studying whether it is safe and effective to use laparoscopic surgeries for cancers of the stomach, colon, rectum & liver. It may prove to be as safe and work as well as standard surgery while cutting less and causing less damage to healthy tissues (being less invasive).

Biopsy of Cancer before Surgery

Biopsy is procedure to confirm the presence of cancer. It’s not essential before surgery. Usually biopsy is performed when 1. Suspicion is cause other than cancer, 2. When surgery cannot be done for cancer due to advanced stage of cancer or 3. Patient is unfit to undergo surgery. In these situation, biopsy guides for further therapy.

If all investigations suggest that cancer can be removed in totality from body, then biopsy can be avoided in to minimize the risk of spillage of cancer cell during biopsy procedure.

There is variety of way to perform biopsies:

Fine Needle Aspiration (FAN) biopsy

Fine needle aspiration (FNA) uses a very thin needle attached to a syringe to pull out small bits of tissue. The needle is guided into the tumor by looking at it using an imaging test, like an ultrasound or CT scan.

The main advantage of FNA is that there is no need to cut through the skin, so there is no surgical incision.

A drawback is that in some cases the needle can’t take out enough tissue for an exact diagnosis. A more invasive type of biopsy (one that involves larger needles or a cut in the skin) may then be needed.

Core Needle biopsy

This type of biopsy uses a larger needle to take out a core of tissue and done under guidance of imaging test like an ultrasound or CT scan. The advantage of core biopsy is that it usually collects enough tissue to find out whether the tumor is cancer.

Excisional or Incisional biopsy

For these biopsies, the surgeon remove the entire tumor (excisional biopsy) or a small part of the tumor (incisional biopsy).

Preparation for Surgery

Our expert team members shall help you to prepare you for surgery. You are strongly advised to stop smoking, stop drinking alcohol, try to improve your diet, lose weight, or actively exercise before surgery.

Pre-operative testing

In most cases, you will need some tests before your surgery. The tests routinely used include:

Blood tests to measure your blood counts, your risk of bleeding or infection, and how well your liver and kidneys are working. Your blood group type is also be checked in case you need blood transfusions during the operation.

USG/CT scans/ MRI to look at the size and location of the tumors and see if the cancer looks like it has spread to nearby tissues.

Anaesthetic Assessment before Surgery:

Our expert team of Anaesthetist will ask you questions pertaining to your health and to assess your fitness for surgery. You are requested to tell them in detail about your current and past medical ailments, allergic reactions you’ve had in the past and current medicines that you are taking like blood thinning medicine. This medicine should be stopped 1 week prior to surgery.

Informed Consent

Informed consent is one of the most important parts of “getting ready for surgery”. It is a process during which you are told about all aspects of the treatment before you give your doctor written permission to do the surgery.

Getting ready for Surgery

Depending on the type of operation you have, there may be things you need to do to be ready for surgery:

Emptying your stomach and bowels (digestive tract) is important. Vomiting while under anaesthesia can be very dangerous because the vomit could get into your lungs and cause an infection. Because of this, you will be asked to not eat or drink anything starting the night before the surgery.

Laxative: You may also be asked to use a laxative or an enema to make sure your bowels are empty.

Shaving of Operative part: You need to have an area of your body shaved to keep hair from getting into the surgical cut (incision). The area will be cleaned before the operation to reduce the risk of infection.

Anaesthesia

Anaesthesia is the use of drugs to make the body unable to feel pain for a period of time. General anaesthesia puts you into a deep sleep for the surgery. It is often started by having you breathe into a face mask or by putting a drug into a vein in your arm. Once you are asleep, an endotracheal or ET tube is put in your throat to make it easy for you to breathe. Your heart rate, breathing rate, and blood pressure (vital signs) will be closely watched during the surgery. A doctor watches you throughout the procedure and until you wake up. They also take out the ET tube when the operation is over. You will be taken to the recovery room to be watched closely while the effects of the drugs wear off. This may take hours. People waking up from general anaesthesia often feel "out of it" for some time. Things may seem hazy or dream-like for a while. Your throat may be sore for a while from the endotracheal (ET) tube.

Recovery from Surgery

Your recovery right after surgery depends on many factors, including your state of health before the operation and how extensive the operation was performed.

Pain

You may feel pain at the site of surgery. We aim to keep you pain free after surgery with the help of latest and most effective technique or analgesic (pain relieving medicine).

Tube/ Drains

You may also have Ryle’s Tube (tube going through nose to stomach) that drain out intestinal fluid. This tube helps to relieve nausea and vomiting after surgery and usually removed 1-2 day after surgery.

You may also have “Tube” (called a Foley catheter) draining urine from your bladder into a bag. This will be taken out soon after surgery, once you are comfortable enough to go to bathroom.

You may have a tube or tubes (called Drains) coming out of the surgical opening in your skin (incision site). Drains allow the excess fluid that collects at the surgery site to leave the body. Drain tube will also be removed once they stop collecting fluid, usually a few days after the operation.

Leg Stocking / Compression boot

As you are remains in bed on day of surgery, circulation of blood in leg become sluggish that may increase possibility of thrombo-embolism. To minimise it, you will be wearing leg stocking/ pneumatic compression boot to improve your leg circulation thus minimising the risk of thrombolism.

Eating and Drinking

You may not feel much like eating or drinking, but this is an important part of the recovery process. Our health care team may start you out with ice chips or clear liquids. The stomach and intestines (digestive tract) is one of the last parts of the body to recover from the drugs used during surgery. You will need to have signs of stomach and bowel activity before you will be allowed to eat. You will likely be on a clear liquid diet until this happens. Once it does, you may get to try solid foods.

Activity

Our health care team will try to have you move around as soon as possible after surgery. They may even have you out of bed and walking the same day. While this may be hard at first, it helps speed your recovery by getting your digestive tract moving. It also helps your circulation and helps prevent blood clots from forming in your legs.

Our team shall also encourage you to do deep breathing exercises. This helps fully inflate your lungs and reduces the risk of pneumonia. You are advised to take deep breaths and cough every hour to help prevent lung infections. You will use an incentive spirometer (a small device used in breathing exercises to prevent complications after major surgery) 10-15 times every hour.

Going home

Once you are eating and walking, all tube/drains placed during surgery are removed, and then you may be ready to go home. Before leaving for home our health care team shall give you detailed guidance regarding diet, activities, medications & further plan of treatment.

Risks and side effects of surgery

There are risks that go with any type of medical procedure and surgery is no longer an exception. Success of surgery depends upon 3 factors: type of disease/surgery, experience of surgeon and overall health of patients. What’s important is whether the expected benefits outweigh the possible risks.

Doctors have been performing surgeries for a very long time. Advances in surgical techniques and our understanding of how to prevent infections have made modern surgery safer and less likely to damage healthy tissues than it has ever been. Still, there’s always a degree of risk involved, no matter how small. Different procedures have different kinds of risks and side effects. Be sure to discuss the details of your case with our health care team, who can give you a better idea about what your actual risks are. During surgery, possible complications during surgery may be caused by the surgery itself, the drugs used (anesthesia), or an underlying disease. Generally speaking, the more complex the surgery is the greater the risk. Complications in major surgical procedures include:

Complications related to Anaesthesia : Reactions to drugs used (anesthesia) or other medicines. Although rare, these can be serious because they can cause dangerously low blood pressures. Your doctors will watch your heart rate, breathing rate, blood pressure, and other signs throughout the procedure to look for this.

Thrombosis (blood clot) in leg & embolism (blood clot) in lung : Blood clots can form in the deep veins of the legs after surgery, especially if a person stays in bed for a long time. Such a clot can become a serious problem if it breaks loose and travels to another part of the body, such as a lung. This is a big reason why you will be encouraged to get out of bed to sit, stand, and walk as soon as possible.

There are specific complications related to type of surgery. You are encouraged with discuss in detail with our health care team before you give your consent for surgery.

Bile leak

Bleed

Complications related to Major Surgery

Infection : Infection at the site of the wound, lung and urinary infection. Infection risk is more if intestine is perforated before surgery, operated for colon and rectum, stent in placed in bile duct to relieve jaundice or intestinal joint is leaking.

Bleeding : The risk of bleeding during or after surgery is more if patient taking blood thinning medicine till day of surgery or having liver dysfunction. Bleeding during surgery that may cause you to need blood transfusions. There is a risk of certain problems with transfusions, some of them serious. Still, some operations involve a certain amount of controlled blood loss. Bleeding can happen either inside the body (internally) or outside the body (externally). It can occur if a blood vessel sealed during surgery opens up or if a wound opens up. Serious bleeding may cause the person to need another operation to find the source of the bleeding and stop it.

Following treatment, you may feel change in your taste. This improves over a time and we encourage having health food habit like fresh vegetables, fruits and high protein diet.

Exercise

Along with healthy food habits, we also encourage for exercise. Exercise improves your health in different ways: It improves your heart and circulation, makes your muscles stronger & makes you feel happier. You should do your regular activities like walking, and rather increase day by day. Weight lifting and strenuous exercise are avoided for initial 2-3 months.

Follow up care

You'll need regular check-ups after treatment for liver cancer. This help to find out any change in your recovery. Sometimes liver cancer comes back after treatment. Our health care team will check for return of cancer. Checkups may include a physical exam, blood tests, ultrasound / CT scan.

If you have any health problems between checkups, you should contact our health care team. Report to our health care team, if you have any redness/ swelling or discharge of any type of fluid from your operative incision site, pain abdomen, vomiting or fever, breathing difficulty etc.
